Our smaller systems are equipped with a Shurflo pump as a feed pump for the watermaker. The pump head may wear out over time, and a new pump will restore system functionality. A spare Shurflo pump head is the most important spare part to carry for Ventura and Cape Horn Extreme systems. This includes a pump head with heat sink and pressure switch. This is also compatible with older models such as the Spectra 180C, 280C, and 380C. Be sure to check the voltage of your system before ordering.
